A spiky ball made from pink, brown, and blue origami paper.

Tricolour Sonobe

This polyhedron was one of my first modular origami creations, and the pattern is my go-to option to share with others. It is made from thirty Sonobe modules, although if you get bored partway through you can make a triakis octahedron out of just twelve units.
